The title of this piece should really be John de Clay in France as John was not knighted until c1461 by which time he had as a member of the Duke of Yorks entourage left service in France behind.
It is said that John de Clay came from humble beginnings and that his service in France led him to a good marriage and an entry into Herfordshire society, Soldiers,Nobles and Gentlemen, Coss and Tyerman.
However there was a prominent Clay family already in Hertfordshire, that of Sir John Clay who had been the receiver of Edward the Black Prince at his castle in Berkhamstead and there are many other references to Clays in Hertfordshire and a Sir Walter Clay lies buried in a churchyard in Hertfordshire.
In the book The History of Parliament 1439-1509 V1 page 187 it states that John was born in 1415, we know this cannot be correct because in 1421 he was in France, or is it correct because in 1429 we have a John de Clay as an esquire joining the garrison at Rouen, where the Captain is John Clay. If John de Clay was born in 1415, he would have been around 15 years old at this point, an appropriate age to become an esquire.
We also know that Sir John as he became was an advisor to the Duke of york and in France acted as treasurer to his household and they were both of the same age, Richard had been born in 1411. Sir John, in fact went on to serve Richard in England and his son Edward IV.

the herds of the people of Louviers, Godefroy Halton, who commanded the garrison of this town, went out to take back their loot and fell into an ambush where he was taken prisoner with all the men of his company. For a moment, the town of Louviers remained devoid of soldiers and exposed to the greatest danger. At the news of this failure, the lords of the Council sitting in Rouen hastened to send to Louviers Pierre Poolin, lieutenant-general of the bailiff of Rouen, and Jean de Clay, elected, with 6 men-at-arms and 18 archers to horse. A few days later, the siege of Gaillon was decided. It began around May 10, 1424 and continued for two months or more. The garrison capitulated on July 8; she returned the place to the Regent and placed herself “in his grace and mercy.” The English army consisted of 200 men-at-arms and 600 archers.

Henry, by the grace of God king of France and England, to our friends and fathers, the treasurers and general governors of our finances in France and Normandy, greetings and love.

an embassy came to him from King Edward of England, who of the said duke was very honorably welcomed and greatly feasted; it was the chief embassy, sir Jehan Venlocq, grand baron of England wearing the Order of the Garter, with him a knight named sir Jehan Claix, and a very notable law clerk who called himself dean of Bordeauz, who proposed before Duke Phelippe for King Edward; they were accompanied by a notable squire called Thomas Vagant, native of the country of Wales, high esquire of the king's stable.

The established captains were Sir William Breton, Sir Nicholas Burdet, Sir Richard Curson, Sir Thomas Hoo, Sir John Melton, Sir Henry Norbury, Sir William F (twice), John Clay, Fulk Eyton and Thomas Gower. (Hoo and Eyton actually succeeded Talbot as captain of the places in which they acted as lieutenants). Talbot's promotions were Richard Bolt, Willian Cornwalle, Richard Gond, Thomas Eton (or Elton), John Wake and probably Thomas St Thomas Curson and Richard Gower were probably the sons of these.
The established soldiers were John Curzon of Keddleston, Derbyshire who had fought at Agincourt, John Clay of Cheshunt, Hertfordshire, who had been his lieutenant at Rouen, and Thomas Pigot of Roxwell, Essex, who had already crossed the border in 1435 (Wedgwood, p245; CPR, 1429-36, P476).
He retained many established soldiers of fortune, but towards the end of the war those who were successful turned to permanent service as one or both of royals, Somerset and York. (1) Only members of his personal retinue returned to England with him. And indeed, this “brawling company had someone (James, Lord Berkeley) to intimidate. At least five veterans of Talbot's retinue were in Lady Margaret's retinue when she entered Berkeley 1451. These and at least one other probably accompanied her to Gascony, and two others survived to serve her heir. (2) Certainly the return of personal su brought new servants into his affinity, but it is doubtful whether this seriously affected his size or behavior.
(1) Oldhall, Ogard, Clay and Gower, for example, looked to York. Hoo and Scales were also at one time his advisors, but they later turned to Somerset. Sir Richard Harrington was more decidedly Somerset's man. The less fortunate turned to charity after the war. Sir Robert James, for example, who had served in the wars for thirty years or more (and sometimes under Talbot and who had been taken prisoner no less than four times and who, at the fall of Bayeaux, had lost everything he owned), was granted alms to the college of St. George, Windsor, on August 12, 1451 (CPR, 1446-52, P470-
